Because ultrasonic bonding
uses friction and pressure to bond materials directly to each other, Julia Daniel, regional technical coordinator, Emerson, says that it makes the added cost of glue and solvents, as well as the cost for added fixturing and the time for glue to "set-up," unnecessary.
Optimization of Vertical Ultrasonic Bonding
Even though Au wire can be used for ultrasonic bonding
, aluminum is the preferred wire.
In general terms, ultrasonic bonding
uses high frequency sound to generate localized heat through vibration and causes thermoplastic fibers to bond together.
The IC tag inlay will be produced by applying a propritary ultrasonic bonding
Additionally, it works well with post-processing steps such as ultrasonic bonding
, spin welding, adhesive bonding, and heat staking.
is defined as "the use of high frequency sound to generate localized heat through vibration and cause thermoplastic fibers to bond to one another" by INDA, the association of the nonwoven fabrics industry.
Available in 20- and 35-kHz sizes, the modules are said to provide greater flexibility for automation projects using ultrasonic bonding
creates a strong molecular bond that's impervious to moisture and eliminates stitch holes, glue gaps, fraying and unraveling, substantially reducing any risk of damage to the interior contents of the vest."
This project will focus on the collective development of novel ultrasonic bonding
equipment and innovative stretch fibers for the construction of stretch laminates, without the use of hot melt elastic attachment adhesives.
To ensure that Sonobond's equipment satisfies specific requirements, it offers a free, no-obligation ultrasonic bonding
viability test to produce sample assemblies with companies' nonwoven or synthetic fabrics.
Aurizon Ultrasonics has entered into an exclusive license agreement with CERA France to enable the manufacture and sale of its patented rotary ultrasonic bonding
technology to secure elastic strands into nonwoven structures used in articles such as diapers and adult incontinence undergarments.
